* Review of STL iterator + difference_type limitations (half range) compared ↵Sven Göthel2024-05-033-14/+69
| | | | | | | | | | | | | | | | | to size_t index ops and pointer arithmetic Svenson an I discussed the issue and we were a bit puzzled ;-) So it would have been great to have size_type to be unsigned (ssize_t) to simply constrain and harmonize the whole std::vector (etc) operations. Alternatively, an iterator could have been a pointer type, where such operations are at least tolerated despite similar considerations to ptrdiff_t like void *lo, *hi; lo-hi ! In the meantime, if using iterator and a size, stick to iterator and signed size.
* Resolve clang-tidy warnings=error; Notable std::vector<>: size() -> size_t ↵Sven Göthel2024-05-0310-63/+88
| | | | | | | | | | | (unsigned) but iterator and difference_type are signed and losing half of range Because std::vector<>::begin() iterator performs arithmetic using a signed difference_type, we need to use such a signed type here to avoid `bugprone-narrowing-conversions` (LINT) Now, isn't this odd as std::vector<>::size() uses unsigned size_type, aka size_t and mentioned iterator hence lose half the value range possible?

* Lesson 01: Pull up ronding to integer type using a constexpr function.Sven Gothel2022-10-221-9/+22
| | | | | | | | | | Resulting of our group's review, we concluded this increases readability. We also realized that implementing the `dx` (x-axis distance) and `sx` parameter (x-axis scaling) distracts from the original task. However, these are the costs to pay to move to a more 'production like' code. Its application is shown within the `main` function of printing all objects in all sizes aligned to their center.
